Definitions

  • the invention relates to containers and more particularly relates to an insulating container for cooking food with a lower insert for supporting the cooking implement and a cover for the insert.
  • insulating containers are constructed having inserts or support bottoms which correspond to the pot shapes and which are provided with a cover.
  • This construction solved the problem of maintaining the serving temperature of preheated food without any further heating.
  • the disadvantage of such a solution is that the insulating container had to correspond to the cooking pot shape. It was always difficult to remove the pots from the insulating container. Very often the housewife was not able to remove the pot from the insulating container without somebody assisting her by holding the insulating container in place.
  • a further disadvantage was the need to have the correct insulating container for each possible shape of cook pot used in the average household. Furthermore, it has been shown that cooking in such insulating containers does not meet the requirements of increased demands.
  • said insert having a smaller outer diameter than the diameter of the bore of said cover whereby when the first open end of the insert is inserted into the second open end of the cover a slot is formed between the open end of the insert and the open end of the cover, said slot communicating between the bore of the cover and outside of the container;
  • FIG. 1 is a cross-sectional side view of an insulating container 1 embodiment of the invention consisting of an insert 2 and a cover 3.
  • Insert 2 functions to hold a cooking implement in place, for example a cooking pot 5.
  • Insert 2 may have a round shape, so as to correspond to the shape of the cooking pot 5.
  • On its upper side the insert 2 is provided with an incline 7 to accommodate receiving the lower portion of the cooking pot, pans etc. This incline 7 borders a cylindrical recess 8.
  • a removable disc 9 is inserted into recess 8.
  • This disc 9 may be made of asbestos, rubber, glass fiber reinforced plastic or like heat-resistant and inexpensive material. The disc 9 increases the life span of the insulating container 1.
  • the slot 4 prevents the formation of a vacuum inside container 1.
  • the inner shape of cover 3 advantageously corresponds to the shape of a cooking pot or a pan.
  • the inside of cover 3 is provided with a recess 6 to accommodate the lid handle of the cooking pot 5.
  • the upper end of cover 3 may also have indentations 12 to facilitate gripping with one's fingers.
  • cover 3 is so dimensioned that its cylindrical portion encompasses the highest shape of the cooking pot 5 and also the pot handles 16. This can be seen in FIG. 2 which is a view along lines A--A of FIG. 1. It will be observed that the cover 3 is not snug with respect to the outer wall of the cooking pot 5.
  • An empty space 15 is provided between the inner surface of cover 3 and the outside of the cooking pot 5. This feature is advantageous for reducing heat transfer, the formation of an air buffer and it also prevents a jamming of the pot 5 in the container 1.
  • the construction of the container 1 has the following advantages.
  • the embodiment container 1 of the invention may be fabricated from conventional thermal insulating materials.
  • Representative of such materials are synthetic, polymeric resin foams such as foamed urea resins, phenolic resins, polystyrene, polyurethane, polyvinylchloride and the like.
  • the foamed resins are of the closed cell type.
  • the foamed resins will have a weight between 45 and 100 Kp/m 3 , preferably around 60 Kp/m 3 .
  • the foam material will advantageously be resistant to degradation at temperatures of up to 60° C. to 130° C. and preferably at least up to about 110° C.
